av_interleaved_write_frame()：无法分配内存，写入 udp 尾部时出错

我正在将 udp 输入转码为 mpegts udp 输出。几个小时后，ffmpeg 用完了所有 RAM 内存。我不知道问题出在哪里。

命令：

ffmpeg -hwaccel vaapi -hwaccel_output_format vaapi -i "udp://239.100.1.5:1234?fifo_size=1000000&overrun_nonfatal=1" -map i:0x100 -map i:0x101 -vf 'scale_vaapi=w=720:h=576,hwdownload,format=nv12,fps=25' -c:v mpeg2video -b:v 5000k -minrate 5000k -maxrate 5000k -muxrate 7000k -pcr_period 40 -flags:v +ildct+ilme -top 0 -aspect 16:9 -c:a mp2 -b:a 192k -c:s copy -mpegts_service_id 1 -metadata service_name="Transcoded" -metadata service_provider="HD to SD" -f mpegts "udp://239.120.1.2:7006?pkt_size=1316&bitrate=12000000"

有任何想法吗？
